Title: Improvements in detecting mechanisms
Inventor: PEARSON LEONARD
IPC: B65B57/12
Filed: 1960-08-27
Abstract: 983,145. Packaging-machines; shoots. ROSE BROS. (GAINSBOROUGH) Ltd. Aug. 10, 1961 [Aug. 27, 1960], No. 29625/60. Headings B8C and B8S. A mechanism for detecting the faulty feed of articles, e.g. sweets in a wrapping machine, comprises a feeler 24 which, on encountering a sweet in a pocket 12 of an intermittently rotated feed wheel 13, causes a solenoid 43 to be de-energized, thereby allowing a roller 23 to feed a web 15 of wrapper material. The feeler 24 is secured to an arm 26 of a lever 26, 27 pivoted at 28 coaxially with an operating arm 29 carrying a switch 33 which is closable by an abutment 31 carried on the arm 27. The arm 29 is oscillated through members 34, 36 by a cam wheel 38 and roller 37 in timed relation with the feed-wheel 13. Should the feeler 24 contact a sweet in one of the pockets 12, the abutment 31 is held out of contact with the switch 33, thereby de-energizing the solenoid 43 and allowing a web feed roller 23 to co-operate with a lower roller 22. Should the feeler 24 enter an empty pocket 12, the switch 33 is closed and the solenoid 43 energized to raise the roller 23. The web is severed before being fed by grippers 19 into the path of a sweet 11 raised out of its pocket 12 by a pusher 14. The wrapper and sweet are supplied through a folding box 20 to jaws 16 of an intermittently operated wrapping wheel 17. A member 21, reciprocated in timed relation to the pusher 14, holds the wrapper on the sweet.

The polymeric material (b) may be contacted with an inert particulate carrier, e.g. talc or ground quartz which has coated on the surface thereof chlorinated paraffinic hydrocarbon (d). The term "siliceous material" includes glass fibres and cloth, asbestos, mica, silica in the form of sand and glass panels. The glass fibres may be in the form of rovings, yarn, chopped fibres, strands and bundles. The silane and chlorinated paraffinic hydrocarbon can be dissolved in a mutual solvent and be applied from a single bath. Several methods of bonding the treated siliceous reinforcing material and the resins can be used. The reinforcing material may be contacted with the molten polyolefine resin. Laminates of treated glass cloth and polymer film can be heated and pressed. The coated glass fibres can be chopped and blended with resin pellets and powder to form a moulding composition which is mixed in a reciprocating screw and injection moulded to form a resin composite. Alternatively the siliceous material can be coated with the silane (c) and the resin in particle or film form coated with the chlorinated paraffinic hydrocarbon (d), bonding then being achieved by thermoforming or injection moulding. In a modification a blend of the polymer (b) and a particulate carrier which has been impregnated or coated with chlorinated paraffinic hydrocarbon may be formed, this blend heated to the softening point of the polymer and bonded to the silanecoated siliceous material.

Title: Improvements in or relating to thermionic valve pulse generating and modulating circuits
IPC: H03K7/08
Filed: 1945-11-13
Abstract: 603,196. Pulse modulation. McDERMOTT, T, J., and COOP, E. Nov. 13, 1945, No. 30386. [Classes 40 (v) and 40 (vi)] Duration modulated pulses are produced by arranging a condenser to discharge through a constant-current device to produce a saw-tooth waveform, a valve being provided to maintain the condenser charged when conducting, the modulating voltage determining the time after commencement of discharge at which the valve becomes conducting. In the embodiment described, the condenser C1 is charged through valve V2 and discharged by constant-current valve V1, when V2 is non-conducting. A negative-going trigger pulse at pulse recurrence frequency is applied to the suppressor grid of V2 which is rendered non-conducting thereby. It is cross-connected with valve V3 so that a rise in anode voltage of V2 produces a fall in the anode voltage of V3 which is applied to the control grid of V2 to maintain the latter non- conducting. The condenser C1 now discharges through V1 until the cathode of V2 reaches the control grid potential. This point of time is determined by the modulating voltage applied to the control grid of V3. Valve V2 now rapidly becomes fully conducting to re-charge condenser C1 and V3 reverts to its non-conducting state. Rectangular duration-modulated positive-going pulses are derived from the screen grid of valve V2. These may be differentiated and the negative trailing edge derived pulses segregated as phase-modulated pulses. The modulating signal may consist of interlaced amplitude-modulated channel pulses. of a multiplex, system, such as described in Specification 584,729, in which case the triggering frequency applied to the suppressor grid of V2 is the product of the channel pulse recurrence frequency and the number of channels.

Abstract: 1,155,462. Centrifugal compressors. CARRIER CORP. July 7, 1966 [July 26, 1965], No.30591/66 Heading F1C. [Also in Division G3] A control system for regulating a gas compression plant comprises a valve 24 in the inlet 22 of a compressor, and a dump valve 30 on the outlet side of the compressor. Servofluid is supplied through passage 35 to a branch passage 36, controlled by a valve 46 in response to the inlet temperature measured at 40. The branch passage 36 is connected to bellows 50 and 106. The pressure in bellows 106 acts in opposition to the inlet pressure fed to a bellows 114 to position a valve 118 whereby the pressure in a branch 116 is proportional to the inlet pressure and temperature and acts on a bellows 126 to control the valve 24. The bellows 50 controls a valve 63 to provide a pressure in a branch line 64 proportional to the temperature. This pressure acts on a bellows 66 in opposition to outlet pressure or reservoir pressure to control a valve 84 which controls the pressure in bellows 98 of the dump valve 30. The pressure produced by valve 84 also acts in a bellows 104 to actuate a switch 105. Closing of the switch actuates solenoids 151, 150 to cause valve 92, 132 to open the dump valve 30 and close the inlet valve 24, this being achieved with a time delay whereby the valve 30 is opened before the valve 24 is closed. Solenoids 151, 150 are also activated by a switch 142 in the event of surge, the switch being closed by the bellows 140, 138 connected to the outlet 26 when there is a sudden change in pressure. The system may be operated as a base load system or an intermittent system by the setting of valve 87, 89, 90, 129, 128 in the system.
